Your question is related to hibernate directly and has nothing to do with jBPM. However to configure the DBCP connection pooling you need to specify the following properties in hibernate.cfg.xml | <!-- DBCP connection pooling options --> | <property name="hibernate.dbcp.maxWait">3000</property> | <property name="hibernate.dbcp.maxIdle">100</property> | <property name="hibernate.dbcp.maxActive">10</property> | <property name="hibernate.dbcp.autoReconnectForPool">true</property> | <property name="hibernate.dbcp.autoReconnect">true</property> | Consult the documentation of DBCP, I remember it was pretty well documented when I used it a while ago View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4066614#...
